YARN-DRYING Macrame.

T0 (ZZZ whom itmay concern Y Be it known that we, THOMAS ALLSOP andWALTER- V. SIBSON, of the city and county of Philadelphia and State ofPennsylvania,

" and RUSSELL B. Lowe and RALPH E. THOM- SON, of the city of Fitc-hburg,countyof Worcester, State of Massachusetts, have in- .vented certain.new and useful Improvements in Yarn-Drying the following is aspecification, reference being had to the accompanying drawings.

It is the object of our-invention to provide a device for drying warpsor similar yarns, in which the said yarns are thoroughly subjected tothe drying action of heated air. This we accomplish by provid-' ing achamber in which heated air is c1rculated and passing the yarns throughthis chamber in a tortuous path, whereby the yarn is subjected for acomparatively long In the accompanyin g'urawings, Figure I,

is a longitudmal section through a drying machine, convenientlyillustrating our invention. Fig. II, is a planview of the same with thetop cover removed. Fig. III, is 40 an enlarged detail view of thefeeding and tension,devices. Fig. IV, is a detailsection on line IV, IV,of Fig. II;

The mechanism thus shown comprises four parts, which we will describesuccessively, to wit: 1. A heating chamber with -1neans for continuouslycirculating therein dry hot air. '2. Means the tortuous progress of thewarp thread i .ough the heating chamber, under proper tension and withefl'ective separation, so as .to prevent entanglement even when the warpbreaks. 3. A tension device for regulating the initial tension at whichthe yarn enters Specification-of Letters Patent.

the chamber. 4. A delivery and folding device by which the dry yarn isproperly stacked preparatory to its use in the warping machine.

The heating cltamber.This comprises a structural framework 1, forming aret'angular chamber 2, through which the yarn pro- :gresses, and as seenin Fig. II, also an offset chamber 3, within which are located a seriesofhea'ting coils 5, which may be supplied with steam or any othersuitable heat conducting'fiuid. Chambers 2, and 3, are.separated by apartition 4:, "and communicate through openings 6, and 7, within whichare respectively mounted a pair of blower fans 8, and 9. These blowersare mounted upon shafts 10, and 11, respectively, and may besimultaneously driven by means of a connecting belt 12 (Fig. II). Thepower may be transmitted in any convenient manner to a pulley 13,mounted on the outer end of the blower shaft 11. tion l, extends upwardto the line indicated at- 14, in Fig. I, thus allowing a space betweenthe top thereof and the cover of the drier. When the fans are inoperation the air is sucked from the coil chamber 3, and blown into theyarn traversing chamber 2, and after circulating therethrough againenters the chamber 3, over the top of the glividing pafidition 4:, aportion escaping at The structural framework 1, is completely incl'osedby sectional panels 15, which may be so constructed as to be readilyremovable to afford easy access to the interior of the drier. Thesepanels. are preferablywonstructed of double walls of sheet :tndtalpacked in between with heat insulating material. In order to render theyarn visible as it repeatedly traverses the chamber 2, we have providedits'end walls 16, with windows 17, provided with glass panes. Thus inthe event of the breaking of the yarn, the operator may readily locatethe fault and repair the break. We thus secure a thoroughly insulated,compact heating chamber, within which the yarn is to. be continuouslyprogressed in a tortuous fashion'so as to effect its tl'lorough dryingbefore is emerges from i chamber.

I

Near the bottom at ,the drier, and adjacent to the lowermost roller otthe series 153, i.) a roller 45, which is mounted upon a shaft t6,having a gear wheel =i'i', receiving motion from a similar wheel -18,mounted on the lowermost roller shaft 1"). The yarn is guided upon theroller to, by a series of tin gers 50, secured to a bar ,L, extendingtransversely acr' the machine directly above the said roller. Aboutmidway of the height of the drier and iuliaeeut to the rollcrs 23, asimilar ba r 5'2, lowing guide lingers 53, is provided for directingandspacing the yarn.

In order to facilitate the spacing of the thread at the top oi? thedrier, we have providcd a grooved roller 53, and a guide comb 56. As ameans for separating the yarn vea tically the intermediate uprights 57,of the fame 1, each support a series o't rods or rollers 08, of brass orother suitable mate rial, whereby the yarn is prevented trou'i saggingand hence trou cntangling during its passage through the drier.

The yarn is fed to the drier iron; the inlhrough an eye 70, in the righthand end wall of the chamber 2, as seen in Fig. I. it then passes overthe roller 42, and procee'he downward and. through the guide comb 51, bywhich it is directed to the roller #5. It then passes horizontallyacross-i the bottom of the Cllflll'b which are adjustably her 2, overthe separating rods or rollers to the lowermost roller of the series 23.it then t 'averses the chamber 2, back and fortlu, alternately passingover the rollers of the series 22, and 23, the several convolutions ofthe yarn being separated by means of the rods or rollers 58, supportedby the intermediate uprights 57, of the frame 1. These mnvolutionsalloccur in the" same vertical plane, and are maintained therein by thespacing comb 52, and also the grooved roller After the yarn passes overthe uppermost roller of the series 23, it is guided by means of the comb5G, to the roller ll, and thence on the roller 42, and then ti allyagain through the guide comb 51, to the roller 45. Thereupon the passageis then again repeated back and forth over the rollers 22, and 23, in asimilar manner to that just explained. This second series ofconvolutions of the yarn over the rollers 22, and 23, is, however, in adifferent vertical plane from that first described. The shift-- ing ofthe yarn is accomplished by means of the guide comb 56, to which itpasses after having completed a series of cm'ivolutions in one plane. Itwill, tlie eforo, be seen that the purpose of the comb at, in additionto that of guiding ot the yarn, is to sure ivuly shift the plane of theconvtdutionsv trout one side of the chamber to the other, until it isready to be discharged through the eye T5. It will thus be seen that bythis method the yarn is subjected to the drying action of heated air,.or a comparatively long period, which results in thorough drying. Thismethod of passing the thread through sew eral convolutions in differentplanes enables us to secure a. maximum drying action in a minimum space.After thus passing through the chamber 2, the yarn finally emergestherefrom through an eye 7:), near the top of the drier as shown in Fig.II.

Tension device-This has for its object to accurately regulate theinitial tension by which the yarn is fed to the heated chamber, whichtension tends to distribute its it throughout the length of the yarn prgress in through the heating chamber.

Po the right hand end of the drier is secured a bracket (50, which maybe conveniently formed of structural iron for support ing the tensiondevice 61, through which the varn passes before its entry into the.drier. This comprises three bars (32, (33, and M. mounted on a. seriesof parallel channel beams 65, supported by the bracket (30. To the endsof these bars are secured blocks 66, which are adapted to lit and slidein the troughs of the channel beams (5. These beams are each providedwith a series of: apertures 67, to allow the horizontal adjustment ofthe bars (12, 133i, and 64-. \Vhen the desired adjustment has beenobtained, the bars are locked in place val ' messes by pins 69, whichregister with the apertures 6?; V

It will be seen that the tension on the yarn may be increased by spacingbar-68, with relation to the ars 62, and 6 :1, and decreased by bringingthese hers closer to gether. It will be, of course, understood that thenumber of bars employed may be increased or decreased to suit thevarious conditions to which the drier is adapted.

The delivery and folding deoce.ri\1ter emerging from the eye '75, thedried yarn is led to the fingers of a sliding guide 76, which is mountedto reciprocate horizontally upon a rod 77, extending laterally acrossthe top of the bracket 60, and secured thereto;

he guide 76, is attached by means of 2-. connecting rod 78, to one ofthe links of an end less chain 79, which passes over the sprocket wheels80, and 81. The sprocket 81, is mounted for free rotation in a bearing82, mounted upon the beam '83, comprised by the bracket 60. The sprocket80, is similsriy enounted in a bearing mounted on the beam S3 and itsshaft carrles at its other end a bevel pinion 86, which meshes with 1*.similar pinion 87, mounted on a shaft 88, journuled in a bearing 89. Atits other end shaft-8S, carries a gear Wheel 90, which is driven by apinion 91, on a cross shaft 92, which is suspended from the bracket 60,in bez'irings 93. The shaft 92, receives its motion through a sprocket95, thereon, which is connected by means of a chain 06, with a sprocketWh el 97. mounted on the roller shaft 98, jo=.v vale: in bearings 99,mounted upon the bracket 60.

The bearings Q9, are provided With extensions in which is journalcd asecond shaft 100, which through gears 101, and 102, imparts motion tothe shaft 98, already mentioned. Shaft 100, is also provided with e.sprocket wheel, which is connected by means of a chain 103, with asprocket wheel 10%, on the main or driving shaft Bri'veen the bearings99, shafts 98, and 100, :arry rollers 1UJ, and 106, respectively, overwhich the in isguided by means of the reciprocati finger guide T6. Afterleaving the roller 105, the yarn finally passes over tension rollers107, und 108, mounted on shafts 109, and. 110, respectively, Which aresuspended in links 112. The upper ends of the links are loosely mountedupon the ends of the shaft 98, and are adapted to be oscillated by meansof a link 115, pivotally attached to :i'crank 11.6, on the outer end ofshaft 92, as bestseen in Fig. III. 4

The tension rollers 107, and 108, are gear-9d to each other by theirmeshing pinions 120, and 121, respectively. Shaft 110, is positivelydriven by means of a sprocket 122. thereon, which is connected through achuin 123, to u sprocket 1 1, on the shaft It will be seen that the yarni it leaves l l l i l l l the drier is guided back and forth, over troller 106, and by means of the links 1.12, it is simultaneous therebycausing the yarnto be deiin-zi folds upon suitable trucks wl ployed toreceive it.
